The Dornbracht site explains:
For the first time, Horizontal Shower permits showering using the Ambiance Tuning Technique while reclining. The application combines six Water Bars recessed into a broad shower field above a reclining space, along with an eTool as the main operating element. Just as with Vertical Shower, with Horizontal Shower the user can also choose from among a variety of pre-programmed choreographies, offering a range of settings for water temperature, intensity and quantity. The user can decide from among Balancing, Energizing or De-Stressing effects.
